FAQ ~ COMBUSTION ENHANCEMENT

Q. How much gas per minute do we need to run an internal combustion engine?

A. Just to idle a 140 ci (no work) at 500 rpm will take about 3000 liters of Brown's Gas per hour (about 1/2 of requirement if running straight hydrogen). Generating this volume of Brown's Gas (even with our super-efficient electrolyzers) will require about 9 kW of power; which the vehicle alternator cannot physically provide. Even if you put an alternator on the engine big enough to provide the power, it couldn't make enough BG to power itself. It is not practical to make BG to use as an exclusive engine fuel.

Some inventors make a big media splash by running engines on Brown's Gas. The power needed to make the BG is coming from batteries. While this certainly works (and is dramatic), you'd go 5 times farther on your battery power if you powered a simple electric motor instead of going through all the complication of powering a BG electrolyzer and feeding the BG into an inefficient internal combustion engine.

Q. Can I save gasoline by adding Brown's Gas to the motor air intake?

A. This is an excellent use of BG. Studies from authoritative sources have proven that adding BG to the combustion process of carbon based fuel (like propane, gasoline, diesel, bio-diesel and crude) significantly increases the combustion efficiency.

This is because BG acts like a catalyst, lowering the endothermic energy needed for combustion self-propagation. This allows the combustion process to be faster and more complete (lowering emissions). It also allows more of the fuel's potential energy to be released as heat at the right time in the engine cycle (increasing power). And finally, it allows leaner fuel ratios. So the net result is: The same power and performance using less fuel.

As little as 5 liters of BG per hour helps the gasoline combustion process to be more efficient. This is why our HyZor Technology is so effective.

Q. Can Brown's Gas be used in place of propane and or natural gas in such things as a gas grill or a heating furnace?

A. In theory yes, but we don't recommend it. Brown's Gas uses electricity to make, usually costing more than the fuel it is replacing (for space heating applications).

If you have that much electricity (to make Brown's Gas) you're better off just using it directly (in an electric heater) to do the heating.

However, there are two exceptions to this recommendation.

First, Brown's Gas acts as an excellent combustion enhancement to carbon based fuels. Not only does the Brown's Gas cause the flame to radiate more heat, it also allows some of the fuel to be replaced by water. Water to fuel ratios of 90% water are rumored.

Second, we heard catalytic heaters specifically designed to operate on Brown's Gas. It is our understanding that they radiate 4 times the heat that would have been achieved if you'd used the same electricity in a heating element. We will be further researching this option.

Q. Can Brown's Gas run an engine?

A. Gasoline internal combustion engines run excellently on Brown's Gas but don't expect a self-running engine (water alone), because it takes over 10 times the power to create the Brown's Gas than you get out of the engine running on it.

However a slight amount of Brown's Gas can significantly increase combustion efficiency. Mileage gains over 50% have been achieved, with power increase and longer engine life. See the HyZor Technology offered by Eagle-Research.

Q. Can Brown's Gas assist the combustion of petro fuels?

A. Absolutely and this is a good use for Brown's Gas. Our experiments show that even a tiny amount of Brown's Gas makes a noticeable improvement in petro fuel combustion. This is one basis for our HyZor Technology.

Q. Do you have a list of references for satisfied customers who would not mind discussing their experiences with the Brown's gas?

A. We are working to put together such a list. We do not give out people's contact information without their express written permission. Most people are buying or building machines for their own reasons and don't want to be overrun by information seekers.

FAQ ~ JEWELRY

Q. I work with gold and silver. Can I use Brown's Gas to make jewelry?

A. Brown's Gas has been used by jewelers for over 30 years (those ones who have found out about it), as the gas of choice. It is a trade secret because any jeweler who uses BG has a competitive advantage.

It solders, welds, brazes, preheats, plasma spray, anneals, etc. better than any other fuel-gas. It is EXTREMELY precise and has minimal heating of nearby components.

BG is not in widespread use because (until now) the machines were expensive, inefficient and poorly marketed. Our ERXXXX WaterTorch technology is half the price, very efficient and we are working out the best marketing plan BG has ever seen.

Q. When trying to melt some amethyst crystals from a geode sample, why did they just split, crack and pop?.

A. Crystals need to be heated VERY slowly. I found this problem with opals too.

Generally, BG is much more forgiving when used on materials that normally split, crack and pop. I've even heated a rock under water without it exploding from the steam formation. Note: Take care when doing this type of dangerous experiment, use proper safety procedures.

Q. How long do you hold the flame on feldspar to turn it into transparent moonstone?

A. That depends on the quantity of the flame, the quality of the feldspar and the size of the sample. A 6mm (1/4") sized sample of high quality feldspar will 'cook' down in about 10-20 minutes with 1200 l/h.

BG is the only gas in the world that will allow you to shape the semiprecious material into any shape you desire and purify it at the same time.

Q. The time to treat corundum (to make rubies) is 8-12 hours nonstop at 1800-2000 degrees Celsius. Can an ER1200 WaterTorch produce nonstop at the required temperature?

A. Any of our WaterTorches can produce that temperature. The ER1200 WaterTorch can produce 1200 liters per hour continuous duty. Continuous duty means nonstop. Our WaterTorches are designed so water can be added while operating.

FAQ ~ HEALTH

Q. Is the pure gas, that the ER1200 is producing, usable for skin or body safely?

A. If you bubble the gas through clean water, it becomes pure enough to use externally. This is one of the uses for the optional bubbler that we sell.

Q. Can we produce pure drinking water with the ER1200?

A. Yes. Bubble the gas through water to take out the residual lye. Then you can burn the BG (in a torch) to make super pure water. We call this 'new water' and we are getting fantastic testimonials about its characteristics. We are exploring those claims.

The second (and easier) way to enhance water is to simply bubble the BG through the water. In a few minutes some of the special characteristics of BG will have been passed into the water. We are getting amazing testimonials involving internal and external applications.

Since we recommend filling the machine with pure water (too prevent it from accumulating sludge) making pure water wouldn't be a good use for the WaterTorch.™ For that, it is better to use a reverse osmosis system or a distiller. We use the WaterTorch™ to make pure water only when we also want the 'enhancements' that are only achievable using BG.

FAQ ~ DESALINATION

Q. Would desalination by Browns Gas be more economical and/or energy efficient than conventional methods?

A. The short answer is conventional methods are MUCH more economical. Brown's Gas is a very poor choice for purifying water, except in very specific cases where you want a special kind of water.

FAQ ~ TORCH

Q. How many cubic feet of gas will the ER1200 produce?

A. The ER1200 makes 1200 liters of gas per hour. There are 28 liters in a cubic foot. So the ER1200 will make 42.85 cubic feet per hour.

Q. Do you have any experience with micro torches?

A. Yes, they work great. You'll need to 'dry' the gas because water droplets will extinguish the flame in a tiny torch. Use an inline gas dryer that can take the pressures and temperatures associated with a backfire. Most micro torches do not require a very high BG pressure, so backfire pressure spikes are minimal.

Q. How many torches will the ER1200 operate at the same time?

A. That depends on the volume of gas each torch is using. Typically, it'll replace the acetylene used by a single oxy:acetylene. torch when cutting. It'll run 2 'welding' torches when used for brazing and 10 torches when used for soldering.

Q. I would like to hook up 2 torches to the ER1200. Should I add another bubbler and a torch tying it into the existing bubbler?

A. Adding another bubbler is a good idea because it will help prevent a backfire at one torch from seriously affecting the flame at another torch. Put a 'Y' at the ER1200 and put a hose to each torch, preferably through a bubbler for each torch. The type of 'Y' we use has a valve on each 'torch' leg and is commonly available at welding supply shops.

FAQ ~ CUTTING / TORCH TIPS

Q. We tried to cut several items and the process is very slow. Why does it seems to melt them not cut them?

A. Think of the BG flame as a 'super' torch. Anything a torch will do, a BG torch will do better. You'll find that if you compare the BG directly with your conventional fuel-gas, that the BG cuts (and melts) faster. BG won't 'cut' what conventional fuel-gasses won't cut (like a rock). Regular torches barely melt rock; the BG torch melts rock better than any torch in the world.

Conventional torches are generally used for two types of cutting, flame cutting and oxygen assist cutting.

Flame cutting is usually used for thin materials with no oxygen assist. BG is a superior flame cutting gas. It allows pin point precision and will bore through nearly any material on earth.

Oxygen assist cutting is generally used only on metals that contain a significant percentage of iron. This is because the oxygen actually causes the iron to oxidize (burn). BG is a superior fuel-gas for cutting because it contains a significant portion of 'new' (or radical) oxygen which oxidizes iron faster than bottled oxygen. The BG flame cuts iron about 25% faster than any other conventional fuel-gas (also using 30% less oxygen) and it makes a precision cut without overheating the iron.

Q. What size torch tip should be used to cut rusted steel?

A. We recommend to remove any rust. If you are cutting rusty iron, the BG will do it more reliably and with less spitting, popping and missed cuts than conventional fuel-gas.

We recommend using 'flush' type tips. 'Recessed' tips will heat up because the flame will touch the metal.

Assuming you are using the Victor brand of torch: Use a #0 torch-cutting tip for up to 1 inch of steel (sometimes thicker). A #2 tip should be good to cut at least 4 inches of steel which is the maximum recommended depth for the ER1200. Even then we recommend the extra capacitor option.

Q. Can I speed up the time it takes to preheat steel cutting?

A. The volume of gas makes a big difference on preheat time. At 2000 L/h, it preheats faster than oxy/acet. A notch with a chisel helps by making an edge that will preheat faster.

There is a fine point when the metal is first ready, if it is missed, then it oxidizes and takes a LOT more heat to melt the oxidized layer, which Brown's Gas can do.

You do want a lot of volume to preheat fast, but only a little volume to actually cut. BG allows the best of both world's with what we call a 'preheat' apparatus. This is a valve assembly that allows a huge volume of gas for fast preheat (preheats twice as fast as acetylene) , then cuts back to efficient volume for the actual cut. We provide the plans to assemble a pre-heat apparatus to customers who have bought one of our WaterTorches and request the plans.

Q. Is slag produced with BG as with oxy/acet. cutting?

A. Similar technique, no or almost no slag. Slag or 'dross' is made when there is too hot a flame for the material being cut.

Q. What can I do about too much slag when cutting steel?

A. Too much slag means the cut is too hot. Too much fuel gas or moving too slow are the most common causes. You must either use less volume of gas, a smaller torch tip or hold the torch higher off the steel. BG is best in thick steel. Another 'trick' is to angle the cut so that the torch is cutting through more (thicker) material.

Q. When do I add oxygen to cut steel?

A. You have to wait for the steel (iron) to be at oxidation/ ignition temperature. Usually this is when a few little sparks are flying out. If you add oxygen too soon, it will 'cool' the iron, instead of causing it to burn.

Q. What pressure should the oxygen be set at?

A. Same pressures you'd normally use for acetylene.

Q. I know that the BG can melt metal; is the oxygen or air simply needed to blow the molten metal out of the way?

A. Common misconception. The fuel-gas simply brings the steel up to oxidation temperature. Adding oxygen at this temperature causes the steel to literally burn (oxidize). So the oxygen actually is doing the 'cutting'. You do want to use enough oxygen pressure so the gas velocity removes the molten slag as you are burning through the steel.

BG is slightly different than ALL other fuel gasses because the oxygen it contains is 'new' (very reactive) and causes the steel oxidation to take place at least 25% faster.

Q. Have you tried to use compressed air in conjunction with the Water Torch instead of oxygen?

A. Yes we have. Too much nitrogen in air and it cools the cut to below combustion temperature. The oxygen is required to cause the iron to 'burn' (oxidize quickly) that's how you cut iron with oxy-fuel. The fuel gas heats up the iron to the ignition point, then the oxygen actually allows (a portion of) the steel to burn, creating the heat to melt the rest of the steel.

With conventional fuel gasses, you could shut off the fuel-gas once the cut is started and it will continue at about the same speed. With BG, if you shut off the BG, your cutting speed will be reduced by 25%, to 'normal' cutting speed.

Q. Can BG cut without oxygen?.

A. You can cut thin metal with no oxygen, but after about 1/8" thick we recommend oxygen assist. BG uses about 40% less oxygen, than other fuel gasses, during cutting. This is because BG doesn't need oxygen in the pre-heat flame, uses a smaller torch tip (less kerf) for cutting any given thickness of metal and cuts 25% faster.

Q. What cutting operations can Brown's Gas be used for?

A. BG only 'cuts' iron, using the same equipment and techniques as any other fuel-gas. It does cut about 25% faster and the cut is of higher quality. The cost of cutting is significantly reduced, not only because BG is less expensive but because labor time is reduced.

Q. How does cutting with Brown's Gas compare to plasma?

A. Not as fast in thinner metal, break even about 0.75" thick. Much faster in thick metal. Practically zero consumables and torch maintenance. Considerably less electricity required. Can only 'cut' iron.

Q. How does Brown's Gas compare with laser cutting of metals?

A. Not as fast in thinner metal, break even about 0.25" thick. Much faster in thick metal. Can only cut iron.

Q. How fine a kerf is possible when cutting with Brown's gas?

A. Finer than all other oxy-fuel cutting. Because of the laser-like flame, you can use smaller tips to cut the same thickness of metal. Smaller tips also use less oxygen to cut the same thickness of metal.

Q. Is anyone else having problems cutting steel?

A. No one that knows how to use a conventional torch has problems cutting steel with BG. Try to find someone with expert cutting skills, to teach you.

There are a few things that are a little different, like:

1) Holding the torch higher, because the flame cones are longer and

2) Do not to add preheat oxygen to the flame, because the BG already has all the oxygen it needs to burn. Keep the preheat oxygen valve shut off. Except for torch cutting, there is seldom any need to use bottled oxygen.

Q. While cutting iron, what would cause the flame to keep blowing out?

A. Either the BG or the Oxygen pressure is set too high.

Q. Is oxygen required for cutting all ferric containing metals?

A. Yes, but thin metals (of all kinds) can be cut without oxygen.

FAQ ~ BRAZING

Q. With the BG, it is not possible to reduce the flow of oxygen to prevent oxidation when brazing. Is there a solution?

A. Yes:

First, in most cases, the BG brazes exceptionally well with no modification whatsoever. I have never had the need to modify the flame (reduce oxygen content) in my own shop. My braze and solder joints are not oxidized. I can braze far faster and easier with BG than I ever could using any of the carbon-based fuel gasses.

Second, if you do choose to reduce the oxygen content of the BG, that is one of the uses for the bubbler. If you put a carbon based fluid like alcohol or diesel in the bubbler, it will use up some of the oxygen as they burn, making it unavailable to 'oxidize' the work. This also makes the flame 'cooler' or less able to do work.

Q. Does the modifier fluid have to be renewed/replaced and, if so, at what intervals?

A. Yes but not often. You'd have to experiment for your application. Depth of fluid makes a difference of how much vapors are produced. You can put valves on the bubbler to adjust how much of the BG flows through it; thus having an 'infinite' adjustment on flame modification. If using diesel, vapors get less as the fluid 'goes dead'. I recommend changing the fluid about every four hours of use.

Q. What does an oxygen bottle have to do with modifiers from a modifier tank?

A. When you add carbon-based fuel vapors to the BG, you may need to add some additional oxygen to burn them. You add it in the conventional method, using the oxygen portion of your torch set. How much you need (if any) is a matter of experimentation in your process.

FAQ ~ WELDING

Q. Have you tried welding cast iron with a piece of cast iron with a different strain of iron than the rod?

A. We can weld any cast iron, cast steel to itself or mild steel using the plain (no flux) cast iron rod. Welds are very strong and have great resistance to breaking due to temperature changes.

Q. When we are ready to weld with a WaterTorch, is it as if we were using a regular welding set up with two tanks supplying gas and oxygen?

A. You do use a regular welding setup, but you do not need to use the oxygen hose or valves (so you just keep them closed), because all the oxygen you need for the flame is already a part of the gas.

The only time you add additional oxygen is when you are actually cutting steel. All other applications like preheating, soldering, brazing annealing, flame drilling, flame polishing, plasma spray, etc. are done with just the gas from the WaterTorch, needing no additional oxygen.

Q. I tried to weld steel, and as you said it can't be done - the flame oxides the metal. Any suggestions for aluminum?

A. You need the flux core aluminum welding rod. It welds aluminum extremely well.

Q. Where can I find Tungsten rod?

A. Welding supply store. Used as welding electrodes. Pure tungsten has a green stripe on one end.
